The first modern method for making coffee using a coffee filter—drip brewing—is more than 125 years old, and its design had changed little. The biggin, originating in France ca. 1780, was a two-level pot holding coffee in a cloth sock in an upper compartment into which water was poured, to drain through holes in the bottom of the compartment into the coffee pot below. Coffee was then dispensed from a spout on the side of the pot. The quality of the brewed coffee depended on the size of the grounds – too course and the coffee would be weak; too fine and the water would not drip the filter. A major problem with this approach was that the taste of the cloth filter would add itself to the pot of coffee whether cotton, burlap or an old sock – transferred to the taste of the coffee. Around the same time, a French inventor developed the “pumping percolator”, in which boiling water in a bottom chamber forces itself up a tube and then trickles (percolates) through the ground coffee back into the bottom chamber.
A coffee percolator is a type of pot used to brew coffee by continually cycling the boiling or nearly-boiling brew through the grounds using gravity until the required strength is reached. Coffee percolators once enjoyed great popularity but were supplanted in the early 1970s by automatic drip coffee makers. Percolators often expose the grounds to higher temperatures than other brewing methods, and may recirculate already brewed coffee through the beans. As a result, coffee brewed with a percolator is susceptible to over-extraction. Percolation may remove some of the volatile compounds in the beans, resulting in a pleasant aroma during brewing, but a less flavor some cup.
Today the multi-cup system is still the most common way to provide gourmet coffee. Diamond Beverages offers pot-brew multi-cup coffee systems and thermal-brew multi-cup coffee systems. It also happens to be of the most affordable and eco-friendly systems. There is a verity of reliable machines that will prepare multiple cups of coffee in the matter of minutes. All of the machines that we carry are commercial machines. These machines have a 40 year history and are a perfected system that is crafted to create the perfect temperature and velocity of water to provide the perfect cup of Joe.
